Very few would know that Patparganj, literally standing tall with its numerous housing societies, witnessed a battle in 1803 that defined the subsequent history of Delhi, and India too. Or that Tis Hazari, usually teeming with worn-out, anxious litigants at its famous district courts, may have been named after the 30,000 Sikh soldiers who once camped here. Or that Dhaula Kuan, literally translating to "white well", perhaps referred to a pit-stop used by Mughal emperor Shah Alam II.
